MACHINERY FOR ROLLING PUDDLERS BALLS.

Specification of Letters Patent No. 5,660, dated. July 5, 1848.

To all whom it may concern: Be it known that we, JOHN F. WINSLOW and JOHN SNIDER, of Troy, New York,have

Machines for Rolling or Working Puddlers Balls into Blooms in the Manufacture of. Iron, and that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making part of this speclfication, in which Figure l is a front elevation of the machine; Fig. 2, a side elevation; Fig. 3, a vertical section taken at the line (XX) of Fig. 1 and looking toward the hammer; and Fig. 4, a horizontal section thereof taken at the line (ZZ) of Fig. 1thatis, at a plane above the bed rollers and below the eccentric squeezer.

The same letters indicate like parts in all the figures.

In this machine the operation of squeezing and rolling the ball of iron is effected by an eccentric roller, combined with rollers that form a concave, as secured to John F. IVinslow by Letters Patent of the United States granted on the 18th of December, 1847 but in that machine side cheeks, not

I attached to the concave rollers, were used to prevent the iron from spreading out at the sides. This was, however, found to be de' fective, for the reason that the iron under treatment would be forced in between the rollers and the cheeks and thus injure the machine and its operation.

The principle of the invention for which we now ask letters patent consists 1n preventing the bloom of iron from spreading outtoo far at the ends, and then upsetting the iron, as it is termed, by making one of the rollers that form the concave with a flanch against which one end of the bloom shall bear as it spreads out in the squeezing operation; and also, in combining with the flanched roller for this purpose a hammer, as it may be termed, which acts on the other end of the bloom by a reciprocating motion to strike that end of the bar, and thus effectually upset the iron, and give the required form to the bloom, or bar, or block of iron,

during the squeezing or rolling operation.

In the accompanying drawings (a) rep- (c), the periphery of which is cam formed and provided with cogs, as represented in the accompanying drawings, for the purpose of squeezing the ball of iron and forcing out the impurities, and gradually reducing its diameter and elongating it. For a more particular description of the form, principle, and mode of operation of the squeezer, reference is made to the before recited Letters Patent. Below this squeezing roller are arranged two fluted rollers (d, d) whose j ournals are fitted to appropriate boxes in the frame. These rollers constitute the concave on which the ball of iron rests during the operation of the squeezer, cog wheels (6, f, g, h) being employed to connect the shafts of the rollers with the shaft of the squeezer in such manner as that the peripheries of the two rollers ((Z, d) shall turn in the same direct-ion, and that of the squeezer in the reverse direction, and thus cause the ball or mass of iron, during the operation of squeezing, to rotate about its axis, or nearly so, the requisite power for this purpose being communicated to the machine from some first mover in any efficient manner. One of the bottom rollers (Z) has a strong flanch (2') on one end whic projects sufliciently to pass within the periphery of that part of the squeezer which acts on the iron, after it has been so much elongated as to have one of its ends approach the flanch, and therefore toward the end of the operation of the squeezer that end of the bloom or mass of iron which is toward this flanch will be upset by it and properly formed.

On the side of the machine opposite the flanch (2') is a hammer (j) on the end of a the end of the bloom. A strong helical spring surrounds the bar (70) of the hammer, one end bearing against one of the collars (Z), and the other against the back of the hammer, so that its tension will always force the hammer toward the flanch (z') of the roller (cl). And toward the outer end, the said bar (is) is provided with a spur (m) the inner face of which is slightly rounded to bear against the face of a cam so formed that at each revolution of the bottom rollers it gives the hammer two blows upon the bloom; and at every revolution of the rollers the spring is liberated and the hammer strikes the bloom, and thus upsets the ends, the flanch in this part of the operation performing the ofiice of an anvil. The face of the cam 1s then made in the form of an inclined plane to draw back the hammer preparatory to another operation.

Instead of forcing the hammer toward the bloom by a spring and drawing it back by a cam, this arrangement may be reversed by making the spring simply of sufficient length to draw back the hammer, and reversing the cam that it may force the hammer toward the bloom at the required time, and if desired a lever, operated in any desired manner, such as by a cam or crank, may be used to operate the hammer instead of a cam, and under this latter modification the spring may be dispensed with altogether, by connecting the hammer bar with the said lever.

Having thus described the principle of our invention, its mode of operation and construction, and the various modes in which we have contemplated the application of the principle by which it may be distinguished from all other things before known, what we claim as our invention and desire to secure by Letters Patent, is

1. The employment of a fianch on one of the rollers of the concave, and rotating with it, to prevent the bloom or block of iron from spreading out, and to upset it, substantially as described, when this is combined with the eccentric or cam formed squeezer, as described.

2. And We also claim the employment of the hammer to strike and upset the bloom or block of iron, substantially as described, when this is combined With the flanch that performs the oflice of an anvil, substantially as described, whether the saidflanch be used in the combination herein described or in any other effecting the same purpose.
